Data and specifications subject to change without notice. IR AUTOMOTIVE DOCUMENT NUMBER EN-0346 El Segundo, CA Provisional Specification for the Power Module 11867-E01 A. Application The module's application is to supply power to the trapezoidal brushless DC motor in Electric and Hydraulic Electric Power Steering (EPS and HEPS) systems, by switching power to the three phases of the motor. B. Module Characteristics/Components Tambient = 25C unless otherwise specified. The electric circuit schematic is shown in schematic diagram EN-0345. With reference to the electrical circuit schematic, the reference designators of the inverter die are UH (Q1), VH (Q3), WH (Q5), UL (Q2), VL (Q4) and WL (Q6) - HEX 4.0, 40V (IRFC2804). Electrical interfaces to battery The module gets battery power through B+ and GND terminals. All current switched to the motor by the power module is supplied from these terminals. Power module physical outline is shown in EN-0244. Electrical interface to the three phases of the motor. The module's terminals U, V, and W, provide the electrical interface with the three phases of the motor. Electrical interface to the control circuitry. The electrical interface between module and control board is achieved through fourteen pins. Pin designation is shown in the electrical schematic EN-0345 and the Power Module drawing EN-0244. Mounting features. The power module is to be mounted using a thermally conductive adhesive and screws between the module and the steering housing. - - - Current Sense Resistor Current sensing is achieved through a low inductance, 0.3 m shunt resistor, which is connected between the ground terminal GND and the source of 3 Low side MOSFETs. Accuracy of the current sense resistor is +/- 1%. Accuracy of the current signal will be based on characterization results upon customer approval. Current sense resistor value is not fixed. Upon customer request and IR approval, modules with different current resistor values (i.e. 0.5 m, 0.7 m, 1 m) can be provided. Temperature sensor One NTC Thermistor positioned beside a MOSFET, provides a temperature reading that can be correlated to the Junction temperature of that MOSFET. The NTC Thermistor is 10K @25C +/-5% with a B-value 3380K @25C +/-3%. Upon customer request and IR approval, modules with different thermistor values can be provided. 4 of 10 IMPORTANT INFORMATION - This document is provisional. Data and specifications subject to change without notice. IR AUTOMOTIVE DOCUMENT NUMBER EN-0346 El Segundo, CA C. Handling Recommendations The Power Module 11867-E01 is an ESD (Electro Static Discharge) sensitive device. It should be handled in accordance with "IEC 61340-5-1 Electrostatics- Part 5-1: Protection of electronic devices from electrostatic phenomena- General requirements" and "IEC 61340-5-2 Electrostatics- Part 5-2: Protection of electronic devices from electrostatic phenomena- User Guide" "IEC" is the "International Electrotechnical Commission". These documents are equivalent to the European Standard (EN) and the British Standard (BS) of the same numerical designation. These are standards that describe the special requirements and precautions needed when handling ESDS (Electro Static Discharge Sensitive) devices. The Power Module 11867-E01 is built with large FET's when compared with typical discrete components. These large FET's also provide improved ESD performance versus the typical discrete components. The Power Module 11867-E01 provides ESD performance above 2 kV against the Human Body Model (HBM; 100pF, 1500), above 2 kV against the Machine Model (200pF, 0), and 2 kV against the Charge Device Model. 5 of 10 IMPORTANT INFORMATION - This document is provisional.
